The Title is the Question so…
Is it possible to mirror Polypainting from one side to another ?
I got the polypaint from a texture but the ztool doesn’t have mirrored UV so it was only transfered on one side.
If I understand your question properly you could try this.
If your model was symmetrical over the x axis you could clone it and then do a mirror in the x axis so your polypainting was on the other side.
Then you could append the clone with the mirrored polypaint to the original, mask off the side of the model you are happy with and then project the polypaint from the mirrored model to the original.
This could be done with project all.
Does that make sense? Things all ways sound more simple in my head un till I try to write them down.

Try Mirror and Weld, it will mirror your Polypainting
